FRANK B. YINGLING, OF HAMILTON, OI-IIO, ASSIGNOR TO COLUMBIA MIACHINE TOOL CO., OF HAMILTON, OHIO, A CORPORATION OF OHIO.

SHAPER.

Application led March 19, 1920. Serial No. 367,221.

To all wiz/m t may concern: y

Be it known that I, FRANK B. YINGLING, a citizen of the United States, residing in Hamilton, Butler County, f)liio, have invented certain new and useful Improvements in Shapers, of which thefollowing is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to improvements in shapers and is especially concerned with the provision of means for supporting and adjusting the position of the work table so as to bring any one of a plurality of its faces Y into the field of operation of the cutting tool,

The objects of my invention are- First: To provide a shaper construction of the type referred to, Comprising means for rotatably supporting the work table sothat any one of a plurality of its faces may be brought into position to hold work in the proper position relative to the cutting tool.l

Second: To provide meansV of the character described, comprising means whereby Y the work table can be adjusted both vertically and horizontally, irrespective of its angular adjustment.

Third: To provide a shaper of the conn struction referred to, in which both ends of the work table a're rigidly sup-ported, and

Fourth To provide means of the character described comprising a rail and a guide coacting therewith for support-ing the outer end of the work table, and permitting of-its horizontal adjustment, so constructed as to protect the sliding faces from chips which would tend to cause inaccuracy in cutting.

These and other objects will definitely appear as the description progresses, reference being had to the accompanying drawings, in whichl4`igure 1 is a side elevation of my improved shaper, certain portions thereof being omitted.

Figure 2 is an end elevation of my improved work table, and

Figure 3 is a view partially in section, and partially in side elevation, showing the details of construction of my improved work table, certain parts thereof being bro-ken away.

Throughout the several views, similar reference characters will be used for referring to similar parts.

Referring to the drawings, reference character 1 indicates the column of a Shaper having a. sole plate 2, the forward end of which extends outwardly beyond the end of the work table as will be referredto later on. Reference character 3 indicates the usual ram. Reference character indicates the 'rail mounted, for vertical adjustment in the usual manner, upon which is slidably mounted the saddle 5 which can be adjusted in a horizontal plane in the usual manner.

The parts thus far described are merely conventional and may be modified, as desired.

Secured to the outer face of the saddle 5 by means of the screws or bolts 6 is a hollow cylindrical boss 7 provided with the spaced cylindrical bearings 8 and 9, and having the gear ring segment 10 formed thereon intermediate the two bearings. A pinion 11 is mounted upon a shaft 12 journaled in the work table, the outer end of the shaft 12 projecting through the forward end of the work table and being angularly conformed, as shown at 13, to receive the socket of a. wrench. By rotating the pinion 11, the work table can be angularly adjusted about its axis so as to bring any one of the three of its faces into the iield of operation of the cutting tool.

The lower edges or corners of the central workface are beveled, as shown at 12S/to provide stops for limiting the rotation of the work table aboutits axis, these stops being adapted to co-act with the stops 13 of the bracket 18. A set screw 14 co-acts with t-he bearing 8 to lock the work tablein its adjusted position.

For the purpose of supporting the outer end of the worktable to prevent deflections or vibrations thereof, and consequent inaccuracy in the work, I provide a standard 141 which is secured to the outer extended end of the sole .plate 2, as referred to above. This standard is provided with a pair of vertical spaced guideways 15 for receiving the bolts 16, by means of which the horizontal rail 17 can be vertically adjustably mounted upon the standard 14. The rail 17 slidably supports the bracket 18 which is secured to the outer end of the boss 7 by means of the screws 19 or in any other desirable manner, the inner face of the bracket 18 being provided with a cylindrical boss 20 fitting within the open end of the boss and providing a firm support for the same.

It will be noted that the bottom ot the bracket is so formed, as shown at 18, as to completely cover the rail 17 and somewhat longer than the rail 17, as a result of which the rail 17 is protected against chips which might otherwise lodge on this rail and cause inaccuracy in the adjustments ot the wor-lr table. l also provide a slide '121 which is secured to the lower end ot the bracket 18 by means ot screws Q2. or in any other desired mannen which co-acts with the lower ,tace ot the rail 17 to secure the bracket 1S rigidly to the rail 17. The circular edge 03 ot the bracket 18 may. it desired, be pro.

ed with a graduated scale to indicate the angular adj ustment or the work table.

lVhile 1 have described the details oi1 the preferred embodiment oit my invention. it is to be clearly understood that my invention not limited to these details, but is capable other adaptations and modiications within the scope of the appended claims.

Having thus described my invention, what l claim is:
